Zentimes · ferinazumaDEV — Generative Engine Optimization
Generative Engine Optimization backed by technical SEO and real software + security engineering. I make ChatGPT, Perplexity and Google AI Overviews cite you — then I measure whether it worked. Search my own work and you'll find it surfacing in AI answers. That's the whole pitch: dogfooded, not promised.
I map the prompts your buyers actually type into ChatGPT and Perplexity, run them live, and hand you a gap map: where you're invisible, who's being cited instead, and a prioritized, plain-English fix list.
I ship the fixes, not just advise. JSON-LD / Schema.org, citable content structure, crawler access for GPTBot and Google-Extended, clean SSR. The technical layer marketing agencies can't build — because it's code.
A tracked prompt panel re-run every month across ChatGPT, Perplexity and Google AI. Plain-English report: where you now appear, what moved, who overtook you. The measurement almost nobody else offers.
The foundation GEO stands on: production websites, semantic HTML, structured data, speed and crawlability. Built by a dev with a security background — reversible, documented, nothing that gets you delisted.
A production Next.js brand site I build and maintain — with the AI-visibility work layered on top: structured data, citable page structure and clean crawlable rendering, so the brand is built to be cited by AI search, not just ranked on classic Google.

I'm a software and security engineer. I trained at CEU San Pablo and started out in cybersecurity as an intern at All4Sec — consulting, network infrastructure planning and hardware renewal.
Today I do GEO — Generative Engine Optimization — backed by technical SEO and real engineering. I can both diagnose why an AI engine ignores a site and ship the code, schema and structure that fix it. No agency handoff, no "we'll pass it to the dev team."
And I dogfood it: my work is open — the GEO Handbook (the method) and notebooklm-kb-system (a knowledge system engineered to be machine-readable and citable). Search for them and you'll see the structure that makes content quotable by AI. The rare combo — dev + technical SEO + security — is the point: I make brands citable by AI search and measure whether it worked, white-hat only, so I won't get you delisted. Got something in mind? Let's talk.
Tell me your category and your site. I'll run a free mini-audit — a handful of your real buyer prompts, live across ChatGPT and Perplexity, with screenshots of who's winning them and where you're invisible. Zero risk.
